Archer C20 v5 (US) bricked after flashing bin

I tried to flash my router with https://openwrt.org/toh/tp-link/archer_c20_v5
I download sysupgrade file and tp link oem firmware
and run dd command (i am on linux) and tried to flash the bin file from the router setup page it shows error saying check the size of you file
after that I flashed the sysupgrade file directly now the all router lights are just blinking and router setup page does not open up.

directly, how ?

In my router setup page there is a firmware upgrade option which take a file input for firmware so I just uploaded sysupgrade.bin file dor firmware upgrade

Did you follow the directions on the device info page? Specifically, you need to create a factory image that includes uboot. Did you do that first?

I only found the EU v5 installation here (below), so I'm not really sure if the US version is supported. (maybe someone else can chime in)
